sata-disk module 4 apsdmxxxx55an-axx 3 ? 2012 apacer technology inc. rev. 1.1 1. general description apacer?s sata-disk module 4 (sdm4) is a high -performance, embedded ssd designed to replace the conventional sata hard disk drive. sdm ssd can be pl ugged into a standard serial ata 7-pin connector commonly found in desktops, it-stb, industrial pc and thin client systems. moreover, apacer provides an innovative way for design-in cu stomers to strengthen the vibrat ion-resistance between sdm4 and mainboard. apacer?s sdm4 has a built-in microcontroller with file management firmware that communicates with sata standard interface. this means sdm4 does not require additional or proprietary host software such as flash file system (ffs) and memory technology driver (mtd). this product is well suited for embedded flash storage applications offering new and ex panded functionalities as well as more cost- effective designs, better performa nce and increased reliability. sdm4 series is designed to work at 5 volts and uses a standard sata driver that complies with major operating systems such as microsoft?s windows series. featuring technologies as apacer-spe cific wear-leveling algorithms, s.m. a.r.t, enhanced data integrity, intelligent power failure management, ata secure erase, and trim, apacer assures users of a versatile device on data storage. 1.1 performance-optimized controller the heart of sdm4 is the flash controller, which translates standard sata signals into the data and controls of the flash media. the sata and flash management controller are specifically designed to attain high data throughput from the host to the flash. 1.1.1 power management unit (pmu) the power management unit (pmu) controls the power consumption of sdm4. it can dramatically extend product battery life by leaving the idle part of the circuitry into sleep mode. the pmu has zero wake-up latency. 1.1.2 sram buffer the flash controller performs as a sram buffer to opti mize the host?s data transfer to and from the flash media.

sata-disk module 4 apsdmxxxx55an-axx 9 ? 2012 apacer technology inc. rev. 1.1 5. flash management 5.1 error correction/detection sdm4 implements a hardware ecc scheme, based on the bch algorithm. it can detect and correct up to 16 bits or 24 bits error in 1k bytes. 5.2 bad block management although bad blocks on the flash media are already identif ied by the flash manufacturer, they can also be accumulated over time during operation. sdm4?s c ontroller maintains a table that lists those normal blocks with disk data, the free blocks for wear leve ling, and bad blocks with errors. when a normal block is detected broken, it is replaced with a free bl ock and listed as a bad block. when a free block is detected broken, it is then removed from t he free block list and marked as a bad block. during device operation, this ensures that newly accumulated bad blocks are transparent to the host. the device will stop file write service onc e there are only two free blocks left such that the read function is still available for copying the files from the disk into another. 5.3 wear leveling the nand flash devices are limited by a certain nu mber of write cycles. when using a fat-based file system, frequent fat table updates are required. if some area on the flash wears out faster than others, it would significantly reduce the lifet ime of the whole ssd, even if the er ase counts of others are far from the write cycle limit. thus, if the write cycles can be di stributed evenly across the m edia, the lifetime of the media can be prolonged significantly. this scheme is called wear leveling. apacer?s wear-leveling scheme is achieved both via buffer management and apacer-specific static wear leveling. they both ensure that the lifetime of t he flash media can be increased, and the disk access performance is optimized as well. 5.4 power failure management the low power detection on the controller initiates crucial data saving before the power supplied to the device is too low. this feature prevents the dev ice from crash and ensures data integrity during an unexpected power-off. 5.5 ata secure erase accomplished by the secure erase (se) command, wh ich added to the open ansi standards that control disk drives, ?ata secure erase? is built into the disk drive itself and thus far le ss susceptible to malicious software attacks than external software utilities. it is a positive easy-to-use data destroy command, amounting to electronic data shredding. executing t he command causes a drive to internally completely erase all possible user data. this command is carried out within disk drives, so no additional software is required. once executed, neither data nor the eras e counter on the device would be recoverable, which blurs the accuracy of device lifespan. the process to erase will not be stopped until finished while encountering power failure, and will be continued when power is back on.
sata-disk module 4 apsdmxxxx55an-axx 10 ? 2012 apacer technology inc. rev. 1.1 5.6 s.m.a.r.t. s.m.a.r.t. is an acronym for self-monitoring, a nalysis and reporting technology, an open standard allowing disk drives to automatically monitor their own health and report potential problems. it protects the user from unscheduled downtime by monitoring and storing critical drive performance and calibration parameters. ideally, this should allow taking proa ctive actions to prevent impending drive failure. apacer sdm4 uses the standard smart command b0h to read data from the drive for smart feature as the sata rev.2.6 ata/atapi-7 specifications. ba sed on the sff-8035i rev. 2.0 specifications, apacer smart defines vendor-specified smart attribut e ids (a0h, a1h, a2h, a 3h, a4h-a5h) in sdm4. they represent initial back block count, bad block count, spare block count, maximum erase count, and average erase counts respectively. when the apacer smart utility running on the host, it analyzes and reports the disk status to the host bef ore sdm4 is in critical condition. 5.7 trim made of millions of nand flash cells, ssd can be writt en into groups called pages in 4k size generally, but can only be erased in larger groups called bloc ks of 128 pages or 512kb. these stipulations are partially the source of many performance issues . until an address gets used again, the ssd has to keep track of every last bit of data that?s written on it. the ata-trim instruction tilts the balance in favor of the ssd. trim addresses a major part of the performance degradation issue over time that plagues all ssds. a trim enabled drive running an os with trim support w ill stay closer to its peak performance over time.
